Local Caller ID (CLI) international compatibility

Local Caller ID (CLI) refers to the Caller-ID when making in-country calls. For example, when you call from a French number to a French mobile number, the local Caller ID is the number that the recipient of the call sees as the caller.

Twilio only can guarantee local Caller ID (CLI) for calls made to:

  • United States, Canada and Caribbean Islands with +1 prefix
  • All European Countries

We can not guarantee local Caller ID in other countries around the world. Twilio guarantees International (non-Local) CLI in all countries (e.g. when calling from a US number to a French number).
